SDL Perl
●
Perl bindings para SDL
●
API 1:1 com a libSDL (SDL::*)
●
API açucarada (SDLx::*)

Instalação
cpan> install SDL

Está vivo!
use SDLx::App;
SDLx::App­>new­>run;

Um pouco mais de controle
use SDLx::App;
my $app = SDLx::App­>new(
title => 'meu jogo',
width => 200,
height => 100,
);
$app­>run;

Um pouco mais de controle

Manipulando Eventos #1
use SDL::Event;
sub on_event {
my $event = shift;
if ($event­>type == SDL_QUIT) {
return 0;
}
return 1;
}
$app­>add_event_handler( &on_event );

Exibição

Exibindo... algo :)
use SDL::Rect;
my $rect = SDL::Rect­>new(10,10,10,10);
$app­>add_show_handler( sub {
$app­>draw_rect([0,0,$app­>w,$app­>h],0xFFFFFFFF);
$app­>draw_rect($rect, 0xFF0000FF);
$app­>update;
});

Manipulando Eventos #2
sub on_event {
my $event = shift;
if ($event­>type == SDL_QUIT) {
return 0;
}
return 1;
}

Manipulando Eventos #2
sub on_event {
my $event = shift;
if ($event­>type == SDL_QUIT) {
return 0;
}
elsif ($event­>type == SDL_KEYDOWN) {
given ($event­>key_sym) {
when (SDLK_LEFT ) { $rect­>x( $rect­>x ­ 2 ) };
when (SDLK_RIGHT) { $rect­>x( $rect­>x + 2 ) };
when (SDLK_UP ) { $rect­>y( $rect­>y ­ 2 ) };
when (SDLK_DOWN ) { $rect­>y( $rect­>y + 2 ) };
};
}
return 1;
